Asset Tracing
.webp)
What if you are going through the financial arrangements of a divorce and your ex-partner is hiding substantial assets? It's all too common for ex partners to hide assets and living arrangements to avoid financial losses, pay maintenance and mislead on their financial positions during divorce proceedings. This is where a private investigator is absolutely necessary. We conduct asset tracing and other investigative techniques to prove hidden cohabitation arrangements. Family courts try to make divorce settlements as fair and as reasonable as possible however, there are many factors to take into consideration. When one side is hiding valuable assets or their residency setup, it can hugely affect the outcome of a settlement.

Divorce Settlements & Child Welfare Disputes
Cohabitation surveillance investigations can significantly influence divorce settlements, especially if one party is refusing to pay maintenance. If a spouse is found to be living with a new partner, this may affect spousal support, child support, and property division. Spousal support is often awarded to the financially dependent spouse, but cohabitation can reduce or even remove their eligibility.
Child support may also be affected, as the new partner’s income and shared expenses can be considered. Cohabitation influences property division too, with assets acquired during the new domestic relationship potentially taken into account. While photographic and video evidence gathered from a covert cohabitation surveillance investigation supports arguments in court, the final decision rests with the judge. If you're considering an investigation, consider SPI and work with an experienced family law solicitor to understand how further evidence may impact your case.
